White moths perched inside the white flower of a freshly bloomed Yucca filamentosa plant. These moths intentionally, manually pollinate the flowers of the yucca in return for laying their eggs directly in the ovary of the flower, where the larvae subsist off of some - not all - of the developing yucca seeds. An amazing mutualism! And all the more stunning in that a cultivated yucca in my yard should attract its obligate pollinators immediately upon flowering for the first time since it was planted.

The Prodoxidae are a family of moths, generally small in size and nondescript in appearance. They include species of moderate pest status, such as the currant shoot borer, and others of considerable ecological and evolutionary interest, such as various species of "Yucca Moths".
